I have this issue where iNet Protector doesn't work when I log on with my acount, but it does work with my wife's account

I set iNetProtector to "block everything except..." and when I'm logged on with my account I can access everything on the web, while my wife can only access allowed websites - which is the desired behavior.

I have McAfee Security Center 2011, but I don't like the option of deactivating it.

That sounds really strange. Do you have any significant differences between the both accounts?You can contact us here http://www.blumentals.net/support/wizard.php and with your help we'll try to figure out what could cause the issue.
